SVN Backup Script

This script dumps a subversion repository to a series of compressed files. It uses a local file to remember the last changeset dumped so the script can be used to generate files for backups.

Using the --scp option, the backup files can be generated on one machine and copied to a backup server once dumped.

svnbackup news (2008-06-22)
I've received several patches for svnbackup.sh recently, and an offer to host an RPM version of the code. I decided it probably made sense to go ahead and open the project up to contributors, so I created a project on code.google.com. ...

Unexpectedly broken, and fixed: svnbackup (2007-09-03)
Yesterday Pierre Lemay sent me one of the clearest bug reports I've seen in quite a while, and a patch to fix the problem. He was having trouble with svnbackup duplicating changesets in the dump files. It turns out every changeset that appeared on a "boundary" (at the end of one dump file and the beginning of the next) was included in both dumps. Oops.

When I tested the script, I was able to recover the repository without any trouble. I didn't check 2 cases that Pierre encountered. First, the changeset revision numbers did not stay consistent. When the changeset was duplicated, that threw off all of the subsequent changeset idhttp://www.blogger.com/img/gl.link.gifs by 1. For each duplicate. That in itself is only annoying. The more troubling problem is when a duplicate changeset includes a delete operation. The second delete would fail while restoring, which prevented Pierre from importing the rest of the backup.

In his email describing all of that, he gave me great details about how he had tested, the specific scenario that caused the problem, and then provided the fix!

So, if you are using version 1.0, go on over and download version 1.1 with Pierre's fixes.
Unexpectedly Popular: svnbackup (2007-07-15)
My svnbackup script is the 2nd most popular page on my site, after the PyMOTW home page, and search terms such as "svn backup" and "svn backup script" regularly appear at the top of the list of sources of traffic to my site. The link to svnbackup doesn't appear on the first page of Google's search results, a sign I take to mean that this problem isn't well understood or solved (otherwise, why would so many people page through the search results to find it?).
